, -Be it knownthat l', HIRAM B. CAsPERsoN, a citizen of the United, States, residing at St; Marys, in the county off Auglaize and State of Ohio,`ha've inventedcertain new and useful Improvements in Flood-Grates,` of whichthe following is a full, clear, and Vexact description.

This invention relates to improvements in dood-gates of that class wherein: a horizontally-hung gateis associated with a fender that is arranged to face upstream. j

The object of the present invention is to allow the gate and its fender to assume horizontal confined positions on the rising of the water, so as to float thereon when the flood is at its height, and, furthermore, to provide means which opposes the rising motion of the gate and the fender and is 'also free to be lifted thereby on an increase in the volume of the flood, thus minimizing all liability of injury to the parts.

With these ends in view the invention consists in the novel combination, construction,

and arrangement of parts, which will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part 'of this specification, in which similar characters of reference indicate corresponding-parts in all the gures.

Figure 1 is a plan view of a flood-gate ern-` bodying my invention and shown in its closed v normal position. Fig. 2 is a longitudinal section in the plane indicated by thedotted'line 2 2 in Fig. 1. Fig.l 3'is'a similar sectional View showing the gate and the fender associated therewith in their raised positions When acted on by the iiood. Fig. 4 is a detail perspective view with the gate partly broken away and in section in order to more clearly illustrate the manner of hanging the gate and the means for guiding the buffer-bar.

5 6 designateparallel walls preferably constructed of planking and disposed on opposite sides of the cut through which the stream may ficw,'or, if desired, these Walls may be built up of brick against opposite banks of the stream.

7 7 designate a pair of battens or guide-bars which are secured to the inner opposing faces of the parallel walls. These guide-bars or battens are disposed directly opposite to each Vinclined position.

other, andfeachbar is provided with vertical s lot or-groove 8, the same opening through the upper end vof the bar and terminating at its lower end in a stop-'shoulder 9. (See Figs. 3 and 44.,) Y

An inclined iiood-gatelOis arranged between the parallel walls to Aoccupy theV position indicated by thefull lines in Figs. 1 and 2, and at its opposite side portions this'gate 10v is provided with notches 11,adapted to loosely receive the battens or bars V7. v.The gate isprovided with the laterally-extending trunnions 12, which are made fast with the gate and extend through the notches 11 thereof. These trunnions are fitted loosely in the slots or guideways 8 of the vertical battens, and normally said trunnions rest upon the shoulders 9, whereby the gate is hung at a point intermediate of its length, so as to turn on a horizontal axis, the latter being aorded by the trunnions 12, and at the same time the gate is freeto rise or fall-in a vertical direction, because the trunnions 12 may travel in the slots or guideways S of the stationary bars or battens. With this gate is associated a buifer-bar 13, the same arranged in a horizontal position across the gate and normally held in thez path thereof by means of guide- `bars 14. Theseguide-bars are fastened to theopposing side walls 5 6, and they are provided with vertical slots 15, in which are loosely received the end portions of the buffer-bar 13. The Alower ends of the slots terminate in shoulders 16, which, as shown by Figs. 2 and 3, are located some distance above the gate 10 when the latter is in its normal The slotted bars 14 maintain the buffer-bar a suitable distance above the gate and in the path ofthe latter; but when the water partly fills the space between the walls 5 6 the gate 10 is raised to a substantially horizontal position, thus bringing the said gate into contact with thebuffer-bar 13. The Weight 'ofthe buffer-bar opposes the continued upward movement of the gate; but when the iioodreaches its height and the gate is carried in an upward direction by its trunnions traveling in the slots 8 of the bars 7 this buffer-bar 13 is free to rise 'with the gate, because its end portions are slidably received in the slots of the guide-bars 14.

Assuming that the stream iiows in the di- IOO rection indicated by the arrow in the drawings, the inclined gate 10 is adapted to extend in the direction of the flow and to face downstream. With the gate is combined a fender 16, the same being inclined in an opposite direction to the gate and adapted to face upstream. This fender is provided at its lower edge with a series of slots 17, through which the water is free to iiow in the normal position of the parts. The fender, like the gate, is provided at a point intermediate of its length with notches 18, adapted to loosely receive the battens 19, which are fastened to the opposing walls, said battens having the vertical slots 20,which terminate in the shoulders 21. The fender is also provided with the trunnions 22, which are loosely received in the slots 20 and which are adapted to rest upon the shoulders 21, thereby pivotally supporting the fenderin its inclined position and allowing said fender to assume a horizontal position when the iood reaches its height. The upper end of the inclined pivoted fender is beveled or reduced, as indicated at 16, and this end of said fender is disposed beneath the upper edge of the inclined gate l0, whereby the fender is overlapped by the gate, and the latter is adapted to ride upon said fender for the purpose of raising the fender when the pressure of water against the gate operates to raise the latter. It will be understood that the fenderis held in its lowered positson by the engagement of its upper end with the corresponding end of the gate; but when the gate is raised by the action of the water its upper end bears down upon the upper end of the fender, thus turning the fender on the axis afforded by its pivots 22 and making the fender and the gate assume horizontal positions. On the increase in the volume of water the fender and the gate are free to assume the horizontal positions and to rise to the top of the water, thus assuming the position shown by Fig. 3, wherein the parts are not liable to injury by the action of the water or by any rubbish that may float thereon.

23 designates a buffer-bar which has its end portions slidably confined in tho grooves 24, which are provided in the guide-strips 2.5', 5o

the latter being fastened to the opposing walls at one side of the bars 19. This buffer-bar is held in a raised position above the fender by the slotted g-uide-bars, and said buffer-bar lies in the path of the fender, so as to oppose the continued upward movement thereof. When the fender, however, rises and floats on the water in the manner represented by Fig. 3, the butter-bar is free to give in'an upward direction, because it will travel in the slots 24 of the guide-bars.

Having thus described my invention, I claim as new and desire to secure by Letters Patent` 1. In a flood-gate, the combination of a gate hung to turn on a horizontal axis, and a buffer-bar disposed in the path of the gate and adapted to yield to its upward movement.

2. In a Hood-gate, the combination of guideways, a gate having trunnions slidably received in said guideways, a buffer-bar disposed in the path of the gate, and means for slidably confining the buffer-bar in operative relation to said gate.

3. In a Hood-gate, the combination of pairs of guideways, a gate having trunnions slidably fitted in one pair of said guideways, and a fender also provided with trunnions which are slidably received in the other pair ot said I guideways, said gate and Athe fender being free to turn on a horizontal axis, and either of said parts being adapted to rise and fall in the guideways.

4. In a flood-gate, the combination with a horizontally-hung gate, of a fender mounted to turn on a horizontal axis, and having overlapping relation with the gate, a buffer-bar disposed in the path of said fender, and means for confining said buffer-har in place.

In testimony whereof I have signed my name to this specification in the presence of three subscribing witnesses.
